There are a few things you need in order to vandalize a car. The first is a tool, such as a knife or screwdriver. The second is an object that can be used to scratch the paint or plastic of the car. The third is someone who knows how to do it right - someone who has done it before and knows what they’re doing. Finally, you need some patience. In order to get away with vandalism, you’ll need to do it over and over again until the car is covered in scratches and dents.
